Description
Technical field
The present invention relates to a kind of medical disinfecting articles for use, specifically a kind of medical disinfecting gel.Be mainly used in medical hands sterilization.
Background technology
We know that the hospital infection problem becomes increasingly conspicuous, and have become the public health problem that solution is badly in need of in hospital.The medical worker is in numerous and complicated medical treatment, nursery work, and many work are all accomplished by hands, and the various on hand number of bacteria of medical personnel are often many than other crowds, and the microbial contamination of hands is quite serious.Cross infection due to medical personnel's hand contamination is to cause one of main risk factors of nosocomial infection.This process though hospital's operations routine is all washed one's hands; But medical personnel's the present situation of washing one's hands allows of no optimist; There are the medical personnel about 50% under the situation of not washing one's hands, to be engaged in curative activity; Main cause is that medical personnel's inconvenience in various operating process is washed one's hands or washed one's hands and do as a mere formality, and worrying in addition frequently washes one's hands and sterilize produces stimulation and xerosis cutis to skin, and therefore most handwashing disinfections are in unconscious state.
Massive epidemiology investigation confirms that hands is the arch-criminal who propagates hospital infection, wash one's hands and aseptic technique is that the blocking-up medical personnel cause propagating the key link of infection through hand operated, it also be the most basically, the most cheap, the most simple and easy to do means.The medical disinfecting gel has the washing of exempting from, rapid-drying properties, quick-acting, Disinfection Effect is held characteristics such as effect, has been widely used in hand hygiene sterilization and the sterilization of surgical operation remote holder.At present the medical disinfecting gel sold of market mainly is serve as mainly effective disinfection composition with trichloro hydroxyl diphenyl ether (triclosan) and ethanol; But on April 15th, 2004, the report first of London The EveningStandard caused that people can cause the extensive concern of potential health risk to the use of triclosan.The EveningStandard reports according to the research of the Dr. Pe2ter Vikesland of Virginia, US Polytechnics, remains in the chlorine reaction in the water in triclosan meeting and the tap water processing procedure, generates chloroform (chloroform).Chloroform is a kind of moderately toxic organic compound that has, and can get into body through digestive tract, respiratory tract, contact skin, mainly acts on the central nervous system, has anesthetic action, and can damage heart, liver, kidney.Zoopery finds that chloroform has high fetal toxicity and slight teratogenecity, can induce white mice that hepatocarcinoma takes place.
The appearance of " superbug " at present lets the people again sight transferred on the resistance.As far back as on August 6th, 1998, the Dr.Stuart Levy of U.S. Tufts University write articles on Nature Journal (Nature), pointed out excessively to use triclosan class antibacterial may cause the Drug resistance of antibacterial, and generation can be resisted the novel bacterial of triclosan.One piece of paper of authorities,medical magazine " lancet " publication on August 11st, 2010 warns that researcher has been found that a kind of " superbug ", and it can let malignant bacteria become incomparably powerful, resists nearly all antibiotic.At present, this " superbug " imported Britain into from South Asia, and spreads to the whole world probably.Britain causes the superbug NDM-1 of at least five dead cases, invasion North America, because of most of antibiotic is developed immunity to drugs, probably pasts medical help after the infection.BMH announces that Britain has entered on developing the way of antibiotics, but scientist warns that possibility can not have in 10 years the effectively new antibiotic of NDM-1 is occurred.
Summary of the invention
Technical problem to be solved by this invention is the deficiency that overcomes above-mentioned prior art; Provide a kind of prescription rationally, stable performance, easy to usely, refreshing clean have good bactericidal effect fast, reliable for effect; Do not injure skin, do not have the medical disinfecting gel of potential health risk.
The technical scheme that the present invention solves the problems of the technologies described above employing is: a kind of medical disinfecting gel; It is made up of o-phenyl phenol, ethanol, thickening agent, wetting agent, pH regulator agent, deionized water, and the quality percentage composition of various compositions is an o-phenyl phenol 1.0 ~ 5.0%, ethanol 55 ~ 65%; Thickening agent 1.0 ~ 5.0%; Wetting agent 3.0 ~ 8.0%, pH regulator agent 1.0 ~ 3.0%, surplus is a deionized water.
The present invention preferably forms proportioning (quality): o-phenyl phenol 2.0%, and ethanol 60%, carbomer thickening agent 1.5%, propylene glycol 2.0%, glycerol 3.0%, triethanolamine pH regulator agent 2.0%, surplus is a deionized water.
Thickening agent of the present invention can be selected hydroxypropyl emthylcellulose or materials such as carboxymethyl cellulose or carbomer or sodium alginate for use.Wetting agent of the present invention can select 1 for use, one or both in 2-propylene glycol, the glycerol.PH regulator agent of the present invention can be selected materials such as sodium hydroxide or triethanolamine for use.
The present invention is main effectively active component with the o-phenyl phenol, and as the agent of cleaning corrosion-proof and sterilization, selecting ethanol for use is the cooperative effect agent, because ethanol has good bactericidal property, can work in coordination with the effect that plays quick sterilization with o-phenyl phenol.The present invention has good gelling performance through adding thickening agent, wetting agent, pH regulator agent.Against existing technologies, the present invention fills a prescription rationally, stable performance, easy to use, refreshing clean quick, has good bactericidal effect, and is reliable for effect, do not injure skin, do not have potential health risk.Be specially adapted to the medical hands sterilization of washing one's hands, wipe.
